Noctern can print door tickets and receipts on a Boca-brand thermal ticket printer using Boca's own command language (FGL). This page covers connecting the printer from the Printing card at AdminVenues[venue]Edit. You need the canEditSettings capability.

How printing works

Noctern never talks to the printer directly — the printer sits on your venue's own network (Wi-Fi or wired), not the internet, so Noctern's servers cannot reach it. Instead:

1. Noctern builds the print job (a Boca FGL command stream) for a ticket or receipt.
2. The Door POS app, running on a device connected to the same venue network as the printer, asks Noctern for that print job and sends it to the printer over the network (port 9100).

This means the printer's IP address only needs to be reachable from devices on your venue's network — never from the wider internet.

Connect the printer

1. 1Plug in your Boca printer and connect it to your venue's network (Ethernet is more reliable than Wi-Fi for a fixed box-office station).
2. 2Find the printer's IP address from its network settings menu or a printed network configuration page.
3. 3Go to AdminVenues[venue]Edit.
4. 4Enter the printer's IP address and confirm the port (Boca printers listen on 9100 by default — leave this unless your printer was configured otherwise).
5. 5Confirm your stock size — the height and length of the ticket roll loaded in the printer, and the width of the perforated stub that tears off (defaults match a standard 2.0" × 5.5" ticket with a 1.2" stub).
6. 6Set your policy line — the short line printed on every ticket, e.g. "NON-REFUNDABLE".
7. 7Turn on Also print a customer/signature copy for card sales if you want a second, signable receipt handed to the customer in addition to the merchant copy you keep.
8. 8Click Save Printing Settings.

Send a real test print

The Preview button only shows an approximate text layout — it does not print anything. To confirm the printer itself is working, send a real test print from the Door POS app (open the app on a device connected to the venue's network, go to its printer settings, and choose Send test print). A successful test print confirms the IP/port are correct and the cutter fires.

What prints where

• Tickets print the event title, date/time, seat (or "General Admission"), venue, buyer name (when known), price, the Noctern ticket ID, your policy line, and the event's Sponsor field when set — plus a QR code and barcode on the perforated stub for scanning at the door.
• Receipts print a merchant copy (kept by the venue) for every sale, and a customer/signature copy for card sales when that setting is turned on.
• Reprinting a ticket from the Door POS app adds a REPRINT flag near the venue logo and is recorded in the venue's Activity log with who reprinted it and when.
